Prof Richard Ocaya from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) Qwaqwa  Campus has achieved a significant milestone with a newly patented invention. This patent, developed in collaboration with researchers from Turkey and Saudi Arabia, is the result of work that began in 2017, focusing on a special material known as graphitic carbon nitride.

This breakthrough in temperature measurement technology aligns perfectly with the university's Vision 130 commitment to innovation and addressing global challenges. The new device offers a unique solution to a longstanding issue in the field, providing accurate temperature measurements across an extremely wide range. Existing solutions often require multiple devices, leading to increased costs and reduced accuracy, but this invention simplifies the process.

The device, based on a combination of graphitic carbon nitride and silicon, can measure temperatures from -250°C to 250°C with exceptional consistency and linearity. This range and accuracy set it apart from current technologies, making it suitable for various applications, from standard temperature measurement to specialized settings involving extreme temperatures. It could be especially valuable in deep-space exploration, where equipment faces drastic temperature fluctuations.

The patent underscores the university's commitment to fostering collaborative research, a key aspect of Vision 130. Prof Ocaya attributes the success of the invention to the robust nature of the team, established in 2015. The team is now seeking to commercialize the technology by licensing it to a suitable partner, with organizations like NASA expected to show significant interest.

Prof Ocaya advises other academics considering patenting their inventions to ensure the patent solves a real problem uniquely and is based on sound principles. This makes the invention reproducible and protects it from being copied, assigning exclusive rights to the patent holder. Patenting allows for either manufacturing the devices or licensing them to third parties for royalties and profit. He notes that the main consideration is that the innovation must be practical and solve a specific problem in a novel and commercially viable way. He also acknowledges the challenge many academics face, as the "publish or perish" mentality often leads to choosing scientific articles over patents.

Despite securing the patent, Prof Ocaya and his team continue their research efforts, exploring new possibilities while balancing practical research with academic pursuits. He believes the invention will significantly impact the field of temperature measurement, being integrated into many new designs requiring such measurements.

The university proudly supports this innovative research and anticipates its real-world impact, furthering Vision 130's commitment to increasing UFS's research capacity and capability.

Leader of Bafokeng nation delivers a guest lecture at UFS

Kgosi Leruo Molotlegi, leader of the Royal Bafokeng nation, asked the pertinent questions: Who decides our fate as South Africans? Who owns our future? in the JN Boshoff Memorial Lecture at our university.

He said: “It’s striking that today, with all the additional freedoms and protections available to us, we have lost much of the pioneering spirit of our ancestors. In this era of democracy and capitalist growth (systems based on choice, accountability, and competition), we nevertheless invest government with extraordinary responsibility for our welfare, livelihoods, and even our happiness. We seem to feel that government should not only reconcile and regulate us, but also house us, school us, heal us, employ us, even feed us.

“And what government can’t do, the private sector will. Create more jobs, invest in social development and the environment, bring technical innovations to our society, make us part of the global village. But in forfeiting so much authority over our lives and our society to the public and private sectors, I believe we have given away something essential to our progress as people and a nation: the fundamental responsibility we bear for shaping our future according to aims, objectives, and standards determined by us.”

He shared the turnaround of the education system in the 45 schools in the 23 communities of the Bafokeng nation and the effect of greater community, NGOs, the church and other concerned parties’ engagement in the curricula and activities with the audience. School attendance improved from 80% to 90% in two years and the top learners in the matric maths in Northwest were from the Bafokeng nation. 

Kgosi Leruo Molotlegi stressed the need for people to help to make South Africa a better place: “As a country, we speak often of the need for leadership, the loss of principles, a decline in values. But too few of us are willing to accept the risk, the expense, the liability, and sometimes even the blame, that accompanies attempting to make things better. We are trying to address pressing issues we face as a community, in partnership with government, and with the tools and resources available to us as a traditionally governed community. It goes without saying that we can and should play a role in deciding our fate as members of this great country, and in the Royal Bafokeng Nation, as small as it is, we are determined to own our own future.”
